Floating Fish Breeding Isolation Box — clear, durable, and space-saving solution for isolating ornamental fish and raising fry Key benefits Prevents aggression and cross-breeding: isolates individual fish (e.g., bettas, guppies) to stop fights, unwanted mating, or stress from tankmates. Protects fry and increases survival: provides a controlled space for hatchlings to grow without risk of being eaten by adults or disturbed by other fish. Easy observation and care: transparent sides let you monitor health and behavior; simple access for feeding and maintenance. Space-efficient and compatible: compact, lightweight design fits most aquariums without taking up excessive space. Main features Professional isolation design: floating breeder box keeps fish separated while remaining in the main tank environment, supporting natural water parameters and reducing handling stress. Compact dimensions: 21.5 cm x 10 cm x 13 cm (8.46 in x 3.94 in x 5.12 in) — small enough for most aquarium setups yet large enough to house breeding pairs or a group of fry. Ideal for hatching and rearing fry: provides a secure enclosure for eggs and fry, allowing you to control hatching conditions and minimize predation by adult fish. High-quality material: made from durable, high-transparency, impact-resistant material to provide a stable, reliable, and attractive environment for your fish. Practical applications Isolating aggressive or stressed fish: temporarily separate a betta or injured fish for recovery and observation without removing it from the aquarium. Controlled breeding: keep a female and her fry separate from the rest of the tank after spawning to prevent adult predation and improve fry survival rates. Quarantine small arrivals: isolate new or small ornamental fish (e.g., guppies) for short-term observation before introducing them to the main aquarium. What you get A floating isolation/breeding box sized 21.5 x 10 x 13 cm (8.46 x 3.94 x 5.12 in) Transparent, impact-resistant construction for clear visibility and reliable performance A compact solution that preserves tank aesthetics and water conditions while simplifying fish care Use notes Place the box inside the aquarium so it floats and equilibrates with tank water temperature and chemistry. Check feeding and water flow needs for fry or isolated fish and adjust placement to ensure adequate oxygenation and circulation. This isolation box is a practical, low-stress way to manage breeding, protect fry, and care for individual ornamental fish without extensive tank modifications.
